Chihuahuas can have some stereotypical behaviors that come in their tiny package. They are often called “watch dogs” because they will bark and alert you to any noises or strangers. With the number of Chis we have and have had in our home, the number of watch dogs has been actually low.
Dude is the one and only constant watch dog in our home and he will bark at even a grocery bag blowing in the wind! He guards our back yard like it is his one and only job. They are replacing the roof on the dwellings behind our house and boy had Dude been in guard mode!
